Hi Mike,
I have been trying to colour up a couple of corals for about 18months without success and in a post to another reefer he said to try T5 at the front and back but as I had no room i made a single T5 unit with a blue+ across the middle in btwn leds so it runs front to back 1/ 4' reef bar 2/ 2x orphek atlantics in series 3/ 4' reefbar 4/ single T5 . 5 / 1 x orphek atlantik + a radion pro in series I know its a lot of light but ihave full coverage all over the tank .The corals im trying to improve are a WD and a rainbow monster both frags but the WD was based out with little colour.Both have improved I have taken pics to monitor any progress.
